Commercial space travel is about to become a reality brought about by many private companies bent on taking their earthbound successes into space. The FAA is now open to granting permits to private companies to travel into space. It is hoped that this activity will lead to the colonization of Mars.
Elon Musk of SpaceX has the goal of beginning the colonization of Mars in the next decade. He plans to make commercial space travel and colonization a reality in his lifetime, according to The Washington Post. Mr. Musk is the mastermind behind both Tesla and SpaceX. He is one of the most brilliant minds of our time. An innovator and businessman, Elon has a track record of making dreams a reality and turning his plans into tangible results. Comparing his project to the colonization of America, Mr. Musk explains why he thinks people will agree to move to mars.
It’s a scouting mission. I wonder how much this will cost since this is not a sample return.
Asteroid mining company Deep Space Industries (DSI) has announced the first commercial mission to a near-Earth asteroid, with launch planned by the end of the decade.

1™, the world’s first commercial interplanetary mining mission, will fly to and rendezvous with a near-Earth asteroid to determine its value as a source of space resources. The destination asteroid will be chosen from a group of top candidates selected by the world renowned team of asteroid experts at Deep Space Industries.
Once the spacecraft arrives at the asteroid, the autonomous spacecraft will map the surface and subsurface, taking visual and infrared imagery and mapping overall water content. With the initial science campaign complete, Prospector-1 will use its water thrusters to gently touch down on the asteroid, measuring the target’s geophysical characteristics.
Prospector-1 is a small spacecraft that strikes the ideal balance between cost and performance. In addition to radiation-tolerant payloads and avionics, all DSI spacecraft notably use the Comet line of water propulsion systems, which expel superheated water vapor to generate thrust. Water will be the first asteroid mining product, so using water as propellant will provide future DSI spacecraft with the ability to refuel in space.
But, using an assumption that a wormhole can be found at the middle of a black hole, a group of Portugese researchers modelled how objects like a chair, a scientist and a spacecraft would be able to withstand the journey through it.
‘What we did was to reconsider a fundamental question on the relation between the gravity and the underlying structure of space-time,’ Diego Rubiera-Garcia, lead author from the University of Lisbon, Portugal, said.
An accurate method for spacecraft navigation takes a leap forward today as the National Physical Laboratory (NPL) and the University of Leicester publish a paper that reveals a spacecraft’s position in space in the direction of a particular pulsar can be calculated autonomously, using a small X-ray telescope on board the craft, to an accuracy of 2km. The method uses X-rays emitted from pulsars, which can be used to work out the position of a craft in space in 3D to an accuracy of 30 km at the distance of Neptune.
Pulsars are dead stars that emit radiation in the form of X-rays and other electromagnetic waves. For a certain type of pulsar, called ‘millisecond pulsars’, the pulses of radiation occur with the regularity and precision of an atomic clock and could be used much like GPS in space.
The paper, published in Experimental Astronomy, details simulations undertaken using data, such as the pulsar positions and a craft’s distance from the Sun, for a European Space Agency feasibility study of the concept. The simulations took these data and tested the concept of triangulation by pulsars with current technology (an X-ray telescope designed and developed by the University of Leicester) and position, velocity and timing analysis undertaken by NPL. This generated a list of usable pulsars and measurements of how accurately a small telescope can lock onto these pulsars and calculate a location.

Not so long ago we had to assume that we’ll never be able to travel faster than light. This was based on scientists’ sensible belief that we can travel through space but cannot change the nature of space itself. Then the idea of ‘Warp Drive’ came along to challenge and seemingly change all of the barriers that Einstein’s theory identified. Warp Drive is all about squashing and stretching space — a pretty ambitious task to begin with. So maybe it’s time again to have a look at how far we’ve already come or how close we are to seeing a real warp drive built by humans.
In May 1994, theoretical physicist Miguel Alcubierre finally presented his proposal of “The Warp Drive: Hyper-fast travel within general relativity” in a scientific journal called Classical and Quantum Gravity.
He indeed was inspired by Star Trek and its creator Gene Roddenberry, who famously coined the expression “Warp Drive” to explain the inexplicable propulsion of the Starship Enterprise as prodigious speed was just necessary to enable his fictional space travelers to leap from star to star on their trek.
